# out-of-bounds write when there are many bzip2 selectors | ||
|
||
A malicious bzip2 payload may produce a memory corruption | ||
resulting in remote code execution. | ||
Network services or command line utilities decompressing | ||
untrusted bzip2 payloads are affected. | ||
|
||
Note that the exploitation of this bug relies on an undefined | ||
behavior that appears to be handled safely by current compilers. |
